Waveguide arrays, femtosecond laser-written into fused silica, are a versatile, still well-controllable simulation platform. If the distance between the laser written channels is large compared to the transversal mode size of each waveguide the system can be described by a nearest neighbor coupling Hamiltonian. The possibility to change the propagation and coupling constants in the manufacturing process allows the simulation of a large class of tridiagonal Hamiltonians. In our case the coupling and propagation constants of the waveguide array describing a giant atom system can be found by applying a Lanczos transformation to its interaction Hamiltonian. We report on the current progress of the simulation of oscillating bound states of a giant atom coupled to a waveguide using waveguide arrays as a simulation platform.
